Hey guys.. Will from MC pointed me here.. Had some questions about how well the DF joints would hold up on a front triangulated setup from a deflection and wear standpoint..

Currently have TeraFlex 5" LCG Max Long Arm kit on the Jeep.. It's a triangulated 4 link setup on the front and rear.. Stress forces on the front upper CA joints are well beyond the capabilties of what the 2" joint was intended. (Should have had a 2.5 joint IMHO, but there's not clearances with the current frame and axle mounts to hold the 2.5") I'm going through the rebuildable joint bushings about every 5000 miles to keep the death wobble (DW) at bay. Mostly road miles with some moderate wheeling.. The Flex Joints on the TeraFlex kit are basically the same thing as a Johnny Joint (designwise, even if material isn't), they just use a 7/8 x18 (tpi) shank rather than the 3/4" or 1" shank the JJ comes in.

Anyroads.. Have been considering the Duroflex joints as an option for replacement. I know all the "Pros" about using them from what's on the MC site and now reading here. My concern is using something as flexy as the Duroflex joint could be in a triagulated 4 link. When I say I've been rebuilding due to wear it's due to the DW that's a result of a worn joint.. By most peoples and suspension standards the joints are not really worn out, just worn down, but the lack of any trackbar with my 4 link has a very low tolerance for worn or overly flexy parts before the thing starts with the DW.

Thanks for any input you guys can provide...

Imped, who started the thread, runs a triangulated 4 link rear and 3 link front...

Post up pictures of your front suspension.

OlllllllO

I finished off my front suspension with the MC short arms last night. Installed the lowers last week and noticed a much better ride, although it was just the front and seemed like it magnified the harshness of the rear. Also still had some steering shimmy at 45 and occasional DW. Installed the uppers last night and the difference is magical. Vastly improved the overall ride of the jeep and no shimmy or DW at all, even before alignment and probably with imbalanced tires. But, I was going from a very beat up stock suspension (I could wiggle the upper bushings loose by hand), so I would have been disappointed if I hadn't noticed a significant improvement.

This is my first set of adjustable arms so I don't have as much to compare with as most on JF, but needless to say I'm very happy and can't wait to finish off my rear suspension with them. Going wheeling tonight so I'll see how that goes. I don't expect to be disappointed (as long as I set them up correctly lol).

do you think you could do a launch with the MC joints on pavement to get a good comparison in deflection? In the videos it looks like the MCs have more deflection on acceleration, which is expected, I was just wondering how big the difference really was.

thanks
